Tell us about your experience in developing and working with multi-module systems.

When working with multi-module systems on Android, I have encountered the practice of dividing the application into several modules to improve scalability and code reuse. For example, I would allocate separate modules for the network layer, UI components, business logic, and common utilities.

This approach allows:

• Faster build times, as only part of the project changes.
• Improved code structure and readability.
• Easier teamwork by dividing responsibilities.

In Android Gradle, modules can be configured as implementation project(':moduleName'), which makes dependency management between them straightforward.

Example configuration in settings.gradle:

include ':app', ':network', ':feature_login'

And in app/build.gradle:

dependencies {
    implementation project(':network')
    implementation project(':feature_login')
}
